The flight route between Hanoi and Ho Chi Minh City (HCMC) once again ranked as the fourth busiest worldwide in 2025, boasting a seat capacity of 11.07 million, according to data from an aviation intelligence firm. The route saw a 4% increase in seat numbers from the previous year.
The Hanoi-HCMC route has consistently held a position in the top ten busiest flight routes over the past eight years. Notably, this was its fourth consecutive year in the fourth position.
The average cost of a one-way flight along this route decreased by 11% in 2025, with the current average ticket price sitting at $67. This is highly competitive due to the presence of six carriers operating the route in 2025.

The recent addition of Sun PhuQuoc Airways in the last quarter has added to the competition on this route.
